I need to analize just one minute of a EEG test which last around 50 minutes. The part to be analized is around the minute 10, but I can't access only to that part, because EEGLAB loads always from the begining of the test by default.

When loading the EDF file, EEGLAB has the option: Data range (in seconds) to read (default all [num num]). I have tried here to insert only the time range needed, but I always get the begining of the test.

  • Have you followed [the steps in the manual](https://eeglab.org/tutorials/07_Extract_epochs/Extracting_Data_Epochs.html) to extract data epochs? – Saaru Lindestøkke Aug 30 '22 at 11:10
  • you can do this relatively easy in the GUI. If you plot the data there, you can manually select it and choose to delete it – Douwe Oct 08 '22 at 15:57
  • Thanks @SaaruLindestøkke for your reply. I previously followed the steps in the manual as you suggest – Esteban Mora Tola Oct 17 '22 at 14:42

    Thanks @Douwe for your reply. The solution proposed is actually useful. Anyway, what I did is to select the menu Edit --> Select data, and then I could select only the range that I needed. – Esteban Mora Tola Oct 17 '22 at 14:46
  • if you use ` EEG = pop_clean_rawdata(EEG, 'FlatlineCriterion',5,'ChannelCriterion',0.8,'LineNoiseCriterion',4,'Highpass','off','BurstCriterion','off','WindowCriterion','off','BurstRejection','on','Distance','Euclidian'); % deletes bad chns and bad periods` it auto deletes bad data for you. You might want to check what criterion work for you. – Douwe Oct 17 '22 at 19:22
